NICOP - Unlocking the potential of sodium borohydride as a reversible hydrogen store
Abstract
Unlocking the potential of sodium borohydride as a reversible hydrogen store:Sodium borohydride has been long considered an attractive material for hydrogen storage, because of its high amount of chemically stored hydrogen. NaBH4 also offers an alternative safer solution to the mechanical energies associated with compressed hydrogen. If controlled properly, the theoretical hydrogen storage from NaBH4 is on the order of 7%. Many companies have therefore tried to commercialize NaBH4 forportable electronics and even automobiles. One of the major problems with NaBH4 is that H storage in the material is not reversible. For instance in the Protonex system, the user was supposed to load a new NaBH4 cartridge into the vehicle for every flight, creating a significant logistics challenge.Therefore a more modern approach is being pursued now in hydrogen storage materials, in that that the storage mechanism must be reversible. It is also desirable to minimize their balance of plant, and decrease the temperature at which the hydrogen is released from the NaBH4, attributes that are being tackled by Aguey-Zinsou in his proposal to ONR-G. He leverages his prior work on core-shell materials to decrease the temperatures to release H2 from NaBH4. He now tries to tackle reversibility specifically and his approach is innovative. b. There are numerous potential applications ranging from MC portable power applications to UUV and UAV applications as well as long term ISR operations. All of which are relevant to NRE. c. Code 33 and NRL Energy Research Team d. Enable the reversible storage of hydrogen with NaBH4 under low operating conditions of temperature and pressure, via a nanozing approach aim to control the way hydrogen interacts with NaBH4 at the nanoscale and from this knowledge design viable hydrogen storage materials of high hydrogen capacity
